Reduction of Solid-Supported Olefins and Alkynes

Abstract

The reduction of carbon-carbon multiple bonds in alkynes and olefins supported on a polystyrene resin has been investigated. Homogeneous catalysis by titanocene reagents is effective for the stereoselective preparation of cis-olefins from diarylacetylenes, while the use of copper(I) hydride reagents is effective for the reduction of alpha,beta-unsaturated ketones.
